Do LED Headlights Really Save Much Power? Yes, they do. And they increase options for other accessories without having to think about your stator output.
I’ll use my DR650 for an example, a new 4×6 headlight that I found on eBay
It’s a plug and play, so your low and high beam work as normal. There’s no having to play with wiring and cutting into the stock harness
A lot more light for $18
After this a little test, Watts = Amps x Volts for reference – I’ll use 12.5 volts as my reference number
Stock light on low beam 4.12 amps or 51.5 watts.
High beam stock light 4.56 amps or 57 watts…this bike had a 55/60 bulb.
New LED low beam 0.89 amps or 11.125 watts.
New LED on high beam 1.60 amps or 20 watts.
And to take it one step further, I added a 2000 lumen LED light bar to the high beam (both on full) 2.02 amps or 25.25.
So that’s a gain of 31.75 watts. Those heated grips or heated seat or heated jacket look like a much more viable option now don’t they, without having to do a stator upgrade?
This was a cheap swap, but I won’t call it an upgrade. The primary reason was for riding offroad and having more visibility in on the dusty trails in the southwest. It worked. The light cut thru the dust and was visible from 2 or 3 times the distance that the stock unit was.
If you are DR rider, I did a full write up on this swap and how to make it work with your stock headlight mount. So if you wanted to swap back at any point, it was doable. The details are here in a complete build thread to make DR650 RTW ready
